Jennifer Garner gives dolphin aquatic ecstasy

The 37-year-old actress was researching a role for TV show 'Fantasy Island', in which a dolphin turns into a girl, but admits the friendly mammal got a little too excited.

She said: "I had my feet dangling in the water, and the dolphin came and swam right over my foot. I thought, 'That was so cool!'

The animal then started swimming around Jennifer's leg until it all became a bit too much.

She added: "I said to the trainer, 'I think the dolphin just peed.' He said, 'No, ma'am, no.' "

The 'Valentine's Day' star - who is married to actor Ben Affleck - also revealed she would never pose in her swimsuit now she's a mother-of-two.

When asked if she would considering stripping down, Jennifer - mother to four-year-old Violet and 13-month-old Seraphina - quipped to talk show host David Letterman: "Not enough money in the world, not enough double-sided tape in the world to keep everything in place.

"Clothes are great. I feel great. If you want to see me in a bathing suit, you can go to season something of 'Alias' and I wore a bathing suit for an episode. Go watch that, because that looked good!"
